I like it! Takes some getting used to, but the Warzone mode in particular is terrific. Guerilla Warfare (the plain Team Deathmatch mode) isn't the greatest - it's basically five very small versions of the other maps, and matches can last as little as five minutes on the smallest maps, and then you have a minute to wait after the match before it cycles to the next match, then about thirty seconds of loading time, and thirty seconds before the match starts. So you're waiting almost half the length of the match sometimes - if you were basing the KZ3 MP off of that mode, it would be disappointing.
Warfare though is aweeeesome. You get these epic, long matches where you can wrack up loads of XP on huge maps, with different sets of of objectives that ultimately decide which teams wins and loses.
The new mode with cutscenes is cool too, but I think Warzone really makes the game.
You'll have to play with us soon! Add my PSN ID (Carrotan) - I'll send you an invite to the TAY clan next time I'm on. (Tomorrow, perhaps?)
